<ul><li>Solana uses a peer-to-peer gossip protocol based on the Plumtree algorithm, allowing decentralized communication between nodes to propagate state changes efficiently across the network without relying on a central source.</li><li>Every 0.1 seconds, Solana nodes exchange "push" and "pull" messages, ensuring continuous and up-to-date information sharing to maintain rapid data dissemination and synchronization across the network.</li><li>The gossip protocol consists of four main message types—Push, Pull, Prune, and Ping/Pong—that help distribute data, request missing information, manage node connections, and check node vitality.</li><li>Gossip data is stored in a Cluster Replicated Data Store (CrdsTable), which is continuously updated with incremental updates to the network's state, ensuring data availability and synchronization among nodes.</li></ul>
